I have debugged this issue and believe I have a good understanding of the cause.

I believe that registering the {{FsUrlStreamHandlerFactory}} causes it to 
create an {{FsUrlStreamHandler}} instance for use by "file" scheme URLs. So it 
has effectively replaced the usual {{sun.net.www.protocol.file.Handler}}.

When called upon to parse a string into a URL, the 
{{sun.net.www.protocol.file.Handler}} overrides {{parseURL}} in order to 
replace any {{File.separatorChar}} with '/', before calling the 
{{super.parseURL}}.

The {{FsUrlStreamHandler}} does not include this override. So on Windows, 
backslashes can be passed through untranslated and so we have an invalid URL.

[jira] [Created] (HADOOP-14157) FsUrlStreamHandlerFactory "Illegal character in path" parsing file URL on Windows

[Simon Scott (JIRA)]

Simon Scott created HADOOP-14157:


 Summary: FsUrlStreamHandlerFactory "Illegal character in path" 
parsing file URL on Windows
 Key: HADOOP-14157
 URL: https://issues.apache.org/jira/browse/HADOOP-14157
 Project: Hadoop Common
  Issue Type: Bug
  Components: fs
Affects Versions: 3.0.0-alpha2, 2.6.5, 2.7.3
 Environment: Windows
Reporter: Simon Scott
Priority: Minor


After registering the FsUrlStreamHandlerFactory with the JVM, subsequent calls 
to convert a "file" URL to a URI can fail with "Illegal character in path" 
where the illegal character is a backslash.

For example:
{code}
URL.setURLStreamHandlerFactory(new FsUrlStreamHandlerFactory());
File file = new File("C:/Users");
final URL url = new URL("file:///" + file.getAbsolutePath());
{code}

gives stack trace:
{noformat}
java.net.URISyntaxException: Illegal character in path at index 8: 
file:/C:\Users
at java.net.URI$Parser.fail(URI.java:2848)
at java.net.URI$Parser.checkChars(URI.java:3021)
at java.net.URI$Parser.parseHierarchical(URI.java:3105)
at java.net.URI$Parser.parse(URI.java:3053)
at java.net.URI.(URI.java:588)
at java.net.URL.toURI(URL.java:946)
{noformat}
